Ranger hoodies are just a thick/ multilayer fleece. The Steath is a softshell. I have a few of each. The Rangers are nice but VERY expensive fleece jackets. They do have alot of nice little thought out plans as well. They are DWR or similar coated so they do shed water, like a in a small shower. But they will soak thru. The softshell is fleece inner, with the fabric outer. They call theirs "shark skin" or something like that. It is more water resistant, wind resistant, durable and you do not build up as much electrical charge with the shealth/ spectres as you do with the rangers. I owned one spectre in ME gray, one in ME green, and one in the "elite" Multicam. Also owned a robin hoodie, a ranger in tan and ME grey. I sold the ME green spectre and the Multicam one (The MC one sold for $300 more than I paid for it and I wore it a few times), I still have both ranger hoodies, the ranger hoodie, and the MEgray spectre its more foliage green and I like the color ALOT. I will probably pick up a stealth in black next time they come out, but who knows.
However, as with most fleece/ softshells, they are heavy, and do not really pack worth the crap. I have been wearing a black Arcteryx Atom LT this last season and found it to be a great layer, even when snowshoeing, which I usually wear a layer or two of smartwools under it all. I did get a little cold when stopping for the night or rest stops, but I could easily add another later (like the patgonia R4 fleece) and when needed I could shed it and pack it away in a little space. I scored an atom SV hoodie (twice as thick as the atom lt) for $100 the a few weeks back. But due to the warmer temps, it will just sit in the cold weather bin till the hunt this fall. These types of insulating jackets are better for outdoors I feel since you can lay them up place a gortex shell on them when it rains/ snows, the pack ALOT smaller, weight crap, and cost typically less.
